BeNe Wrote:Added fail2ban and SSL for Mailservice (courier)

I had some problems with SSL for Mailservice.

Code:

VO11919:/etc/courier# apt-get install courier-imap-ssl
Reading package lists... Done

courier-imap-ssl is already the newest version.

Setting up courier-imap-ssl (4.1.1.20060828-5) ...
Starting Courier IMAP-SSL server:0022
/etc/init.d/courier-imap-ssl: xmalloc: ../bash/variables.c:2569: cannot allocate 808 bytes (0 bytes allocated)
invoke-rc.d: initscript courier-imap-ssl, action "start" failed.
dpkg: error processing courier-imap-ssl (--configure):
subprocess post-installation script returned error exit status 2
Errors were encountered while processing:
courier-imap-ssl
E: Sub-process /usr/bin/dpkg returned an error code (1)

But the fix was quit simple. Had to increase the IMAP_ULIMITD in /etc/courier/imapd from the default 65536 to 131072
